<h2>Description</h2>
<h3><a name="BAD_CAST" id="BAD_CAST"></a>Macro: BAD_CAST</h3><pre>#define BAD_CAST</pre><p>Macro to cast a string to an <a href="libxml-xmlstring.html#xmlChar">xmlChar</a> * when one know its safe.</p>

      This is a basic byte in an UTF-8 encoded string. It's unsigned allowing to pinpoint case where char * are assigned to xmlChar * (possibly making serialization back impossible).
